Polymer passivation layer
WebPassivation, in physical chemistry and engineering, refers to coating a material so it becomes "passive", that is, less readily affected or corroded by the environment. … WebIt has been shown that a passivation layer (such as PCBM) placed on top of a perovskite layer can infiltrate the perovskite layer. This can help passivate grain boundaries, 9,10 as shown in Figure 4. Figure 4. Image showing how passivation layers (in this case PCBM) can seep into the grain boundaries (GB) within the perovskite layer.
